MOUNTING.

Patented oet. 1,1912.. 1910. Serial. N0. 552,831.

To all whom 'it may concern.' f

Be it known that I, Lno F. ADT, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass-Mountings; and I do hereby declare 'the following to be a full, clear, and eXactdescription of 'the same, reference being had to the accompanying drawings, specification, and to marked thereon. Y

The present invention relates to eyeglass mount-ings and more particularly to those of the finger-piece type in which the nose guards move toward'the nose under the action of springs, and it has for its object to provide a construction in lwhich the springs are so arranged that they may operate to best advantage withinfa small space anddo not tend to render the mounting conspicuous. Another object ofthe invention is to pr vide for holding the springs to the mounting without the use of separate fastening deforming a part of `this the reference-numerals Vices and to render. the mounting generally convenient for the assembling or detachment of its parts.v

. Figis a plan vView of-a necting the arched To these and other 'ends the invention consists in certain improvements'and combinations of parts all as will be hereinafter more fully described, the novel features being pointed outin the claims at the end of the specification.

. In the drawings: Figure 1 is a front view of one embodiment of the present invention, a port-ion of the mounting being shown in section; Fig. 2 is a plan View of a portion Aof the sam'e mounting in proximity to one of the nose guardsjFig. 3 is-a bottom view of a portion of the same mountingin proximity to one of the guards; Fig. 4 isla central transverse section of the same mounting; portion of another mounting embodying the present improvements; Fig. 6 is of'- the latter embodiment, and Fig. 7 is a central transverse section of the mounting shown in Figs. 5 and 6.

In the embodiment of the invention illusf .tratedin Figs. l to 4 there is employed a support for the lenses comprising preferably an arched or bridging portion 1 adapted to lens attach ing devices 2 and horizontal portions '3 conor bridging portions of the. lens.` attaching devices. The support may also' be provided with .pockets 6 each a bottom view or a portion closed at its top and bottom and opening horizontally, its top wall being formed by a vconnecting jportion -3 and its bottom wall being vformed byl an arm 7 extended inwardly from a Alens attaching device below and in spaced. relation to a horizontal connegting portion 3. Arranged to swing'on the support substantially in a horizontal plane preferably on the upper side are the nose guards embodying in vers 48 extending transversely of the plane of the lens-es. The forward end of each le- .ver may have avertical portion 9 depending downwardly and extending outwardly to provide a finger piece or engaging member which comprises an Lipper pad l0 and a lower pad l1. It is desirable, especially when the distances between the ends of the bridging portion andthe lens bearing portions of the lens attaching devices are4 great, to provide each lever 8 with a stop l2 formed in this instance'by cutting a tongue from the lever stock and bending such tongue downwardly sorthat it will engage the rear of the support. VPreferably the lever 8 -of each guard is formed from Hat stock with its faces horizontally arranged and it carries permanently a pivot pin 13 depending from the under side thereof and turning in bearings in one ofthe connecting portions 3 and an arm 7. arrangement gives a very long bearing for the pivot pin and prevents looseness of the guard. The springs for positioning' the guards are arranged in this instance Within zontally of the springs are facilitated while each spring is supported against vertical movement by the upper and the lower Walls of 'the pocket. in the form of a flat volute or true spiral coil 14, the upper and lower faces of which engage respectively the proximate faces of the connecting portion 3 and the arms 7. The outer end of eaclrcoil may carry an arm 15 which fends forwardly through the open front of a pocket into engagement latter, its forward end heilig interlockcd with the inner vertical edge of the finger piece 9. In order to secure the other or inner end of each coil the latter is provided with a depending projection 1G adapted to enter a horizontally arranged slot- 17 formed in this instance le.

t-he pockets 6 and as the latter-'open horithe introduction and the removaly In this instance each spring is with a guardv in front of the pivot of the' This y BEST AvAuABis COPY of the pocket. This slot d of the spring against the rlower wall 7y holds the inner en turning when t nected with the guar the guard and its pivot' may be' l Withdrawn horizont pocket and separated from the being apparent that ythe pivo passing through the. coil, holds the lattter against removal from the pocket. In the embodiment of I they invention shownin Figs. `5,6,land 7 the vbridging portion 1 and the lens attaching devices the same as in the other' embodiment: connecting portion carries the arm 7**'inj stead 'of thelens attaching device, said arm being formed Ain onepiece'with the connecting 'l portion. This 1s effected in this instance -by theprovision of a rearward extension *Wand a downward extension 7e, the arm 7 B extending forwardly fr'olnthe downwardextension and the outer side o: the forwardly extendingl arm 4being .soldered or otherwisev seeured'to they lens' attaching device' itt/Z?. The.' guards areV substantially the same as those shown in Figs'. l to t1 and the pivot pins 13 turn'both in the connecting portions and the horizontalarmsl'l'f The springsl ofy this embodiment difer .from thoseof the vfirst described enribodiment4 and '.arevin the form of coils 1S of fiat volute or .true spiral form, each tical axis in rear ofthe and between -the` rearwar thev connecting portion, 3

tally arranged arm- Zin rear of inate pivot pin 13, being -forwardly extendingarm 15 detachably i11- terlocltngA at its free end with the vertically {extendingnger ieee 9. The'pinnerend of .the spring is prey ment by,` a projection 16? thereon fitting within a horizontally arranged slot 17,Ithe latter opening in this instance at the front 'ofthe mounting and permitting the re,- moval of the spring. Withment the arm of the sprin is gi length` thus insuring morstrength and the pivot pin being arranged in front of the coil 18 prevents the removal' of' the s the guard is removed. p .In using both embo tion, the inger pieces 9 a each other,- thus effecting the separation of the nose bearing portions of `ythe guards. Upon the release of the finger pieces the noseV hearing lportions move toward eheh other `under the action'of the springs, 'l An eyeglass mounting constructed 1n accordance with this inven located out of conta `,levers 'and mounted tect them from -dust and at the same time, render them inconspieuous. The pockets open horizontally and thus permt but upon removal pin l'the spring ally troni the mounting, it

Qare Each. mounting as the spring the spring ends to be pri which insurev greater strength to the springs without unduly increasing the size of the latter., The connection of each. spring-with 'the support is such that i warnte 'fastening devices are not required v.' of the spring may he effected after the neof its' guard. The guards are so l relatively to the pockets that the latter are hidden and the pivot pins also serve to retain the. spring within the pockets.

lt is particularly ea syto assemble the ishel'd centered and in place by the walls of the pocket 'as soonl as'lt is slipped between them and while the guard lever is 4being applied -whereas' in many Inountings as hitherto "made -it is. necessary that the minute spring beheld in place by the operators' nglers'e one the manipulation otthe ot the parts are puttogether, surfaces formed by the top an V of vthe pocket support the lflat endfacesyof the coil-and hold the' oonvolutons vagainst displacement 'from ,their ltrue p they cannot become distortedor injured in such away as to redutheir eiciency.
